* @class vtkExternalOpenGLCamera
* @brief OpenGL camera
*
* vtkExternalOpenGLCamera is a concrete implementation of the abstract class
* vtkCamera. vtkExternalOpenGLCamera interfaces to the OpenGL rendering library.
* This class extends vtkOpenGLCamera by introducing API wherein the camera
* matrices can be set explicitly by the application.
